Cis correct — UiPath recommends structuringagent evaluationsaroundfunctional setsthat align with expected behavior and edge conditions. This strategy:

Validatesend-to-end logic, not just isolated tool usage

Helps assess whethertool combinationswork as designed

Supportstraceable diagnosisof failures or regressions

In this scenario:

Set 1: Valid Web Search results➝Slack notification (success path)

Set 2: Failed/irrelevant Web Search➝Escalation (fallback path)

Set 3: Edge cases (e.g., ambiguous input, multiple valid matches)

This avoids theredundancyandvolume bloatseen in options B and D.

Option A is too loose — relying solely on random inputs and "LLM-as-a-Judge" introduces risk ofincomplete testing.

Grouping byreal-world interaction patternsmirrors how agents behave in production. It ensures high coverage while keeping evaluation efficient, consistent, andtightly aligned with business logic.
